Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed May 8, 1912. Serial No. 695,838.

T 0 all whomit may concern:

' le it known that I, GEORGE H. \VIEMANN, a. citizen of the UnitedStates, and a resident of the city of New York, borough of Brooklyn, inthe county of Kings and State of New York, have invented a new andImproved Cloth-\Yorking Machine, of which the following is a full,clear, and exact description.

My invention relates to cloth laying ma chines, and is designed for thepurpose 0 winding or bolting quantities of cloth piled up in folds orlayer. each layer being separated from the layer above and below thesame by sheets of paper or similar mate rial; and it: is so constructedthat the sheets of paper or other material in question will becontinuously removed by the machine at the same time that the operationof winding or bolting the cloth is in progress.

To this end my improved machine comn'ises a. framework having boltingapparatus at one end and an adjustable platform at the other end onwhich the pile of folded cloth is laid; and the framework also supportsother suitable mechanism by means of which the sheets of fabric are prenrly disposed of without interfering or hindering the operation ofbolting or winding the cloth. which it is the function of my niachine toperform.

lefercnce is to be had to the accompanying drawings forming a part ofthis specifieation, in which the same characters of reference indicatethe same parts in all the views.

Figure l is a, top plan of my improved cloth laying machine; Fig. 2 is aside clevaiion of a detail of part of the mechanism for engaging andremoving the paper sheets arranged between the folds of cloth; Fig. 3 isa top plan of the parts shown in Fig. Fig. l: is a side elevation of themeans for mounting the guiding rollers of my machine; Fig. 5 is a,vertical longitudinal section of my machine: and Fig. 6 is alongitudinal sectional view of the mechanism by means: of whirh thebeard on which the cloth i bolted by winding is adjustably mounted inposition.

Referring particularly to the drawings. 1 construct the framework of mymachine so as to include uprights 1, preferably eight in number, four oneither side of the same, and these uprights are connected at their lowerends by means of transverse bars or rods 2. The uprights at; the rightend of the machine are slotted as shown at '3, to engage a table orplatform 4: having a top Ii on which is placed a pile of folded cloth(3. This table or platform 4 is provided with studs or guide pins 7which project out ward from its sides to engage the slots 53, theseguide pins being carried by brackets 8 which are preferably formedintegral with the table and are arranged at the sides of the front ofthe same. These brackets 8 have teeth formed along their vertical frontedges to provide a rack, this rack being engaged by pinions 10 on ashaft 9, carried in bearings supported by the framework and operated bymeans of a crank 11. By means of this rack and pinion the height of thetop 5 of the platform 1 can be adjusted. and any suitable means can beprovided for locking the crank to hold the platform 4 in adjustedposition.

The tops of the uprights 1 at the right end of the machine, which may becalled the front thereof, are provided with arms 12 which extendlongitudinally of the framework and have their outer ends connected bymeans of a bent bar 13. This bar is rigidly mounted on the arms 12 andsupports a pair of springs 14 having bearings at their lower ends toreceive a roller 15. These springs extend longitudinally of theframework, and the roller 15 rests upon the top of the pile of cloth tokeep the folds from moving too rapidly when the machine is in use.

16 is an angle-bar which extends between the uprights 1 at the front ofthe machine, the vertical portion of this angle-bar resting against thefront of the cloth pile, and the horizontal portion being located alittle above the top 5 of the platform 4, as shown in Fig. 5. The clothin the pile (3 is folded back and forth, forming layers, and betweenthese layers are arranged sheets of paper 17, in a manner and for apurpose well known to persons skilled in this art.

The numeral 18 represents an inclined way having the lower edge thereofsupported by means of a transverse angle-bar 19, about on a level withthe top edge of the angle-bar 1(3', and its upper edge rests upon atransverse rod 20 passing between the next pair of uprights 1. Part ofthe sheets of paper between the folds of cloth is carried up thisinclined way and delivered into a suitable receptacle adjacent the upperend of the same, when the machine is in use.

21 represents a transverse shaft mounted in hearings in the outer endsof the arms 12; and is a transverse bar extending from one of the arms12 to the other for the purpose of bracing these bars. Similartransverse shafts are arranged in the tops of the first pair of uprights1, and in the tops of the second and third pairs of uprights as well;and the first two of these shafts 21 have two sprocket wheels 23 eachthereon, these sprocket wheels being ar ranged inside of the posts oruprights 1, and at the opposite ends of the shaft. The last shaft 21 hasalso a pair of similarly located sprocket wheels 23 thereon, but thethird shaft has two pairs of s not: {et wheels, as shown in Fig. 1. Theshaft 21 at the top of the second pair of uprights is connected to theshaft 21 at the outer ends of the arms 12 by means of two sprocketchains 20, each of these chains passing over the sprockets 23 at theopposite ends of the shafts, and over and under the sprockets 23 at thetop of the first pair of uprights, the upper section of the chain beingheld in position to engage with the upper side of these last-namedsprocket wheels by means of idle rollers 25 mounted on journals 21 inthe tops of the first pair of uprights, as Fig. 5 plainly illustrates.

The chain 26 comprises a number of ordinary sprocket links, part ofwhich, indicated by the numeral 27, are connected by means of transversebars 28, from which project teeth 29. These teeth 20 are pref-- erablytwo in number for each bar, and they are arranged to pass by the ends ofthe roller 15. These teeth engage the rear ed; s of some of the sheetsof paper 17, and carry them up the incline 18 to deliver them into asuitable receptacle arranged near the upper end of the same. The otherpair of sprockets on the third shaft 21 are connected by a second pairof sprocket chains 213 to the sprocket wheels 23 on the fourth shaft 21at the top of the third pair of posts or uprights. This shaft is a powershaft and has on the ends thereof which project beyond the supportingposts 1, a pair of power pulleys 30, over which the belts which furnishthe driving power are passed. Beyond the pulleys 30 are two othersmaller pulleys 31, which are connected by belts 32 to similar pulleys31 supported on short shafts 33 airried by the last pair of posts oruprights 1, these last-named pulleys serving to actuate the winding orbolting mechanism of my machine,

The numerals 31 represent guide rollers, two of which are supported bythe first pair of posts 1, one beside the other, just above the upperedge of the angleiron 16. One of these rollers may have hearings in thepost itself and the other on the angle-bar 19. A similar roller 31 iscarried by each of the second and third pairs of posts 1; and 31 aresimilar rollers mounted at their opposite ends in longitudinal bars 35joining the members of the third and fourth pairs of posts together.Between the last-named rollers 31 is a large roller 31, and it will beseen that the cloth passes over the first roller 31 at the right, andthen between the same and the next roller beside it, and then under thislast-named roller and the rollers 31 supported by the second pair ofposts. It then passes above the roller 31 of the third pair of posts anddown under the large roller supported by the longitudinal bars 35. Thetwo rollers 34- at each side of this large roller serve to keep a largeportion of the cloth in contact with the periphery of this large roller.

Each of the rollers in question may be mounted in the framework of mymachine by means of a spider 30 having a central bearing receiving thejournals of the rollers, this spider being mounted so as to support thishearing in alinement with the center of apertures 37 in the posts 1, theobject being to support these spiders on the outside of the posts. lVhenone of these I: airings wears out, the spider can be removed and anotherone readily substituted.

The winding mechanism is shown at the left of the frame, and itcomprises a board 38 on which the cloth is wound or bolted, this boltbeing received in the ends of a pair of blocks 35) having receivingrecesses 10 into whic the board 38 fits. These blocks are rigidlysecured to the reduced ends 11 of threaded shafts 12, these threadedshafts being mounted in bearings 13 formed in the upper ends of the lastpair of posts 1, and pas-sing outward through these posts and similarbearings 11 which are supported on the outer sides of the same inalinement with the first-named bearings 13. The shafts 12 are threadedover the greater part of their length, but the internal surfaces of thebearings 43 and 41 are not threaded, as plainly shown in Fig. 6. Each ofthe threaded sh; fts 42 provided with a keyway to enable a driving gear15 to be keyed thereon so as to be able to slide along the same. Thebore of the gear is not threaded, so that there is no other engagementbetween the shaft 12 and the gear 45 except that pro vided by the splineand kcyway above mentioned. The pinion 13 meshes with a pinion 113rotated by means of the pulleys 31, and 47 are hamlwheels havingscrew-thrauled engagement with the threaded shafts 12 ad.- jacent thereduced ends 11. of the same, these handwheels being located inside theposts 1 of the framework forming the body of my machine.

The blocks 39 will be located a certain distance apart, according to thewidth of the cloth and the length of the board on which the same isbolted. When it is desired to move the blocks 39 toward or from eachother, no board being in place, the hand wheels 47 are grasped to makethe threaded shafts 42 slide one way or the other in the bearings 43 and44, the key on the gear 45 moving freely in the keyway in the shafts 42at this time. When they are about the required distance apart, the board38 is inserted and the recesses or notches 40 caused to engage the endsthereof. The wheels 47 are then turned until they come in contact withthe inner ends of the bearings 43, after which the wheels 47 can besecured against rotation on the shafts 42, by means of a locking screwor in any other suitable way. The rotation of the gears 45 then causesthe shafts 42 and the wheels 47, the blocks and the board 38 to rotatewith them.

In operation, power is transmitted to the pulleys 30, rotating thechains 26 carrying the belt 29 and the bolting board 38. This boarddraws the cloth off the pile at the front end of the machine, and eachalternate sheet of paper, beginning with the sheet on top in Fig. 5,will be engaged by the teeth 29 and carried up the incline 18 to bedelivered into a suitable receptacle supported by the framework at theupper end of the trough and above the level of the cloth passing overthe rollers 34 also. The other sheet of paper, beginning with the onedirectly below the uppermost in Fig. will be carried by the folds ofcloth through the rollers 34 supported by the first pair of posts 1, anddropped into a suitable receptacle arranged below the cloth between thefirst and second posts of the framework. Thus the operation of windingor bolting proceeds, and the sheets of paper or the like areautomatically removed and deposited in suitable receptacles forreceiving the same at the same time. While the operation of winding isin progress, the attendant slowly turns the crank 11, gradually raisingthe platform 4, so as to keep the top of the bolt of cloth about on alevel with the lower end of the inclined way or trough 19.

I wish to have it understood that the above description and drawingsillustrate but one embodiment of my invention, and that I do not wish tobe limited to the exact details thereof, but reserve to myself the rightto make such changes in the shape, size and arrangement of the parts asfairly fall within the scope and spirit of my inven tion.
